Process of making artificial fuel.



' UNITED STATES GEORGE W. HERBEIN, OF SEATTLE, WASHINGTON.

PATENT OFFICE.

To all whom it may concern: Y B .'t known that I, GEORGE W. IIERBEIN, a citizen of the United States, residing at Seattle, in the county of King and State as of Washington, have invented certain new and useful Improvements in Processes of Making Artificial Fuel, of which, the following is a specification. v

This invention pertains to a process of making artificial fuel, and has for its object to simplify the manufacture and increase the f efiiciency of the product.

In carrying out the process, I' desirably use a hydrocarbon, such as petroleum oil, a combustible absorbent for the oil, such as Eeat, and a carbohydrate, such as dextrin.

YIGXPGIIIHGIII- I have found that the composltion can be .advantageously made with the proportions of twenty per cent. hydro:

In. he proportions stated {above the ma- -.terials yield a very satisfactory fuel. Where an extremely rich fuel is desired, however, a

pro ortionately greater amount of hydrocar on is added, and to overcome the nonadhesive efiect of the surplusage of oil thus Specification of Letters Patent.

Application filed April 3, 1907. Serial No. 366,077.

Patented Dec. 29, 1908.

intrdduced, I add a salt,such as Sal-soda,

and desirably in solution, which combining withiithe oil renders it less greasy and capablefl of being held together by the gummy characterof the carbohydrate.

Certain substances of. a carboniferous nature, such as coal dust, may be included in the' mixture and held in intimate connection with and as a component of the fuel, thus adding largely to its economic value. In carrying my process into practice, I first heat the hydrocarbon and mix therewith previously dried absorbent material. I then add the carbohydrate, or,'if desired, the carbohydrate and carboniferous material. In supplementing a salt to the above, it is added to the hydrocarbon before the application of heat, thence pursuing the process heretofore described. The mass thus compounded is pressed by molds into briquet's while subjected to the action of heat to assist the binding function of the carbohydrate' What I claim, and ,desire to secure by Letters-Patent, 'is' The herein described process of making artificial fuel which consists in combining in the presence of heat, petroleum oil and dry peat, adding dextrin as a binding agent and subjecting the mixture'to pressure while still in the presence of heat.

g In testimony-whereof I affix-my signature in presence of two witnesses.
